I need Dogsey Peeps Help

I am soon to be starting a study which will involve speaking with lots of vets accross the country to gather as much info as possible, and I would like to ask you all for your help too.
Can you please tell me how many of you that keep your dogs vaccinated has ever had one past or present that has caught one of the diseases it was vaccinated against.
Also I would like to know about any vaccinated dogs you know of that has caught one of the diseases while vaccinated.
For those of you that Titre test I would like to know if any of you have ever had a dog that showed good immunity on a titre test but still caught one of the diseases that had shown good immunity.
Again I would also like to hear the same of any dog you know of that may not be owned by you that is tire tested had good immunity and still caught one of the diseases.
I am going to try and do a poll for this but if I can't you can either reply here or pm me, Simarly if I do a poll I would still like to hear any experiences.
The aim of this is to eventually lobby the insurance companies to change thier stuck in the mud old fashioned views and try to get them to accept titre testing.

If it helps...I haven`t had a dog boostered for 20 years. All my dogs have completed their intial course. None have contracted any of the diseases they have been vaccinated against.

Thankyou, can you just tell me if you have ever titre tested and if so what the results showed.

In all the years I have had dogs (and it's quite a few ) I have had,10 dogs all been vaccinated and none of them ever caugt the disease they were vaccinated against. Only one caught Kennel cough, while in boarding kennels.
Never titre tested (don't know what that is )
